with 133 million gallons of annual production, was purchased, adding value for corn producers and accessing strong markets for ethanol and its coproduct
, dried distiller's grain.
Research by industry, government, and universities is providing new insights into how to efficiently produce, handle, transport, and feed this high-nutrient coproduct
to livestock, including beef and dairy cattle, poultry, swine, and aqua-culture.

This patented process is more cost efficient than traditional methods, like fermentation, and allows the enzymes to be a profitable coproduct
of the corn-based ethanol industry.
The remaining contributions are concerned with industrial products and topics addressed by them include biotransformation of aliphatic hydrocarbons and fatty acids, vegetable oil-based biodegradable industrial lubricants, enzymatic synthesis of functional lipids in organic solvent using lipase, and fermentative production of biopolymers and biosurfactants from glycerol-rich biodiesel coproduct
stream and soy molasses.
